! action_on_fail "Systemd is starting emergency shell" && exec sh -i -l
------->
action_on_fail "Systemd is starting emergency shell"


I think 1st line should be changed to 2nd line. I am wondering why
emergency_shell is not used directly here, instead "exec sh -i -l".

Hi Harald,

May I repost the 2/2 by removing "exec sh -i -l"?

Baoquan
Thanks a lot
